More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the webpage mentioned above.

or run /tmp/curl -Iv https://curl.se, i got:

* Host curl.se:443 was resolved.
* IPv6: (none)
* IPv4: 151.101.193.91, 151.101.129.91, 151.101.65.91, 151.101.1.91

*  CApath: /etc/ssl/certs
* SSL_connect failed with error -308: error state on socket

curl: (35) SSL_connect failed with error -308: error state on socket

On same device/system, build with openSSL one worked fine.

Hello @rampageX

Thanks for this report. Could you please enable debug logging in wolfSSL and share the log? You'll need to add --enable-debug to the wolfSSL configure and add call to turn on logging to curl:
